Villagers build villages

Many people have probably said this already, except for the story, but I don't care lol

I don't know where my memory is bringing this from, but I remember I used to play on a Superflat world on PE, and I spawned a whole bunch of villagers, and I checked in on them every now and then and they were building their own village. I can't tell if this was a very strong dream or a real thing for one day or something. But this would be cool if a group of villagers if left alone long enough would build a village building by building until it's done, and the more villagers the more buildings etc. etc.
